"The National Security Agency is quietly building the largest spy center in the country."

Surveillance, in the way that we know it today, really began when the United States colonized the Philippines in 1898. Thousands of Filipino citizens were indexed according to their families, religious views and potential contributions to rebellion against the U.S. This indexing became a guide for surveillance and the U.S. used the same tactic during WWI. Federal agents developed a database of over 200,000 "enemy aliens" consisting of immigrants, leftists and labor unions. They used this database to track individuals throughout the war.

When it comes to surveillance, these indexes were just the beginning. Watch above to learn how the U.S. grew from databases of individuals to real-time intelligence from companies like Amazon and Google. So, does the U.S. love spying on American citizens and beyond?
